摘要
选用有解析解的圆形油藏,采用无网格方法之一的无单元 Galerkin(Element-Free Galerkin,简称EFG)法求解其压力分布。并将所得结果与其解析解及有限元方法的解进行比较。阐明了使用EFG法的求解过程,同时强调,有技巧地布点,可以提高计算速度,降低对硬件的要求。对处理裂缝等问题,EFG法的优势更为明显。
Based on selecting circular reservoir having analytic solution and adopting one of the no-girding methods-no-unit Galerkin method, pressure distribution can be gotten the solution. The result is compared with its analysis solution and finite element method solution. The paper has illuminated the solution process of EFG method and the method can speed calculation and drop the demand to hardware if rationally arranged the dot. On handling the problem such as fracture, the EFG method has more obvious advantage.
